Daniel,
I'm seeing the same problem here and trying to follow my way
through your kernel config changes. I don't think I have it yet on
this box as I'm seeing a message about rendering being disabled in
Xorg.log.0
c2stable ~ # cat /var/log/Xorg.0.log | grep render
[ 29.017] (WW) RADEON(0): Direct rendering disabled
c2stable ~ #
even though glxinfo says it's enabled:
c2stable ~ # glxinfo | grep render
direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on softpipe
GL_NV_blend_square, GL_NV_conditional_render, GL_NV_light_max_exponent,
c2stable ~ #
Anyway, I'm sure I'll figure it out but I'm curious how you measure
that it's working up to it's potential. I'm getting less than 200FPS
in glxgears. I get >2500 on a cheaper nvidia card so I'm certain this
Radeon 300 can do better.
What do you see in glxgears?
Thanks,
Mark
